Riverbed Optimization System (RiOS) must generate a log event for the enforcement actions used to restrict access associated with changes to the device.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-62939	RICX-DM-000085	SV-77429r1_rule		Medium

Description
Without auditing the enforcement of access restrictions against changes to the device configuration, it will be difficult to identify attempted attacks, and an audit trail will not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action methods may be as simple as denying access to a file based on the application of file permissions (access restriction). Audit items may consist of lists of actions blocked by access restrictions or changes identified after the fact. For RiOS, all configuration changes authorized or unauthorized are logged in the system logs. Log entries include the user that initiated the configuration change for accountability.
